To @ZZ whom, it may concern:

Be it known that I, GEORGE W. LOMBARD, a citizen vof the United States,residing at Testal minster, in the county o1"` Worcesterand State ofMassachusetts, have inventedrcertain new and useful Improvements inGuiding Mechanism for Rattan-SplittingMachines; and' I declare thefollowing to be a description of'my said invention, suiiiciently full,clear, and exact to enable others skilled in the art to which itappertains to'make and use the saine, reference being had to theaccompanying drawings, which forma part of this specification.` Theobject of my present invention is to provide a simple, practical, andefficient mechanism for centering and guiding rattan infront oftheworking tool or cutters in rattanfsplitting machinery, which guidemechanism can be conveniently adjusted, easily operated, andeconomically made and maintained in working condition. These objects Iattain by the mechanism illustrated and described, theparticularsubject-matter claimed boing hereinafter defi`k nitelyspecied.

In the drawings, Figure lis a front view of my improved guidingmechanism, with a portion of the support-bar shown in section. Fig.v

2 shows a plan viewof the guide mechanism in connection with thesplitting-cutter and feedrolls, and Fig. '3 is a vertical sectionthrough one of the guidedevices.

In referring to parts, A designates asupportbar, which rest-s up on twoscrew-threaded studs, B, tted in the bed or table T, to which the ybaris retained by bolts C, which passthrough slots c in the bar and screwinto the bed T, as indicated.`

D D indicate grooved rolls or devices for guiding the rattan to thesplitting cutter or tool S. Said rolls are mounted on studs d, fixedinthe top of swinging arms or guide-blocks E, that are pivoted by studsf to the bar A, upon the top surface of which said swinging blocks havebearing. The pivots f are located sufficiently far in advance of therolls D to permit of said rolls swinging apart, to allowfor'irregulai-ities of the material passing between them. The two blocksE are provided 'with gear-teeth e, which mesh together in the mannerillustrated, so that any Swingin g action of the parts or opening andclosing of the guides will be L uniform at both sides of the centrallin'e, 'thus accurately centering the rattan and directing it into theaxis of the splitting-cutter S, which latter is located lin rear oftherolls D and'sup- .ported on the bed or frame in the ordinary manner. Aat metal spring, H, oi'vC form or horseshoe shape, is arranged aroundthe pivoted ends of the blocks E, with its ends hh pressing inward therear ends of said blocks E at a position below the guide-rolls D, thereaction being from one guide against the other through the spring H.Screws I are arranged through the ends of the spring H, the points ofwhich enter depressions in thepouter surfaces ofthe backs. Said screws Iserve to retain the sprin g in proper relation with the part-s, and alsofor regulating the tension of the spring or pressure exerted by theguides against the material passed betweenthem. Eccentric bushings F arearranged laround the studs or pivotbolts f, within the arms or blocks E,whereby v the parts can be adjusted to takeup any looseness or backlashbetween the gear-teeth e, orfor regulating the relative alignment of theaxes of the guide-arms E with each other. Said eccentrics F are madeslightly higher than the thickness of the blocks E so that the stud f,when screwed down, will clzamp the eccentric bushing F firmly inposition for holding it stationary, while leaving the arms E free toswing on the surface of the bushing.

For facilitating adjustment of theaxial centers, screws m arearranged'in the parts E, that may be turned in against the eccentrics F,for retaining them in relation to the arms E whilel effectingadjustment, and before the studs f are turned down to clamp them inplace by endwise pressure. After the studs f are screwed down, the screwm may be 'loosened to release the parts.

The location of the feed-rolls for forcing the rattan through themachine in relation to the guide devices and cutter S is shown by thecircles K. Said feed-rolls may be constructed and operated in anysuitable well-known manner, as heretofore employed for passing rattanthrough the stripping-machines, and any de-V sired number of rolls K maybe used, the splitting being effected in the ordinary manner.

Vertical adjustment of the guide devices is effected by loosening thebolts C and turning the screw-threaded studs J3 to elevate or depressthe bar A, said studs being provided with neck portions b, that extendup through slots a in the bar A, with their ends iitted to receive ascrew-driver or wrench. The slots a permitlateral adjustment ofthe barand guides, as desired.

By constructing the mechanism as shown and described a very simple,durable, and efiicient guide and centering apparatus is produced,readily adjustable and convenient for use, and not liable to becomederanged or get out of working order.

IVhat I claim as of my invention, and desire to secure by LettersPatent, is

l. In a rattan-splitting machine, the combination, with rolls whichguide thematerial to the splitting-cutter, of the guide-supporting armspivoted for swinging action and connected with each other byintermeshinggear-teeth e, formed 011 arcs of circles coincident with thepivotcentcrs of said arms, and means for adj usting the relativedistancebetween their axes of mqtion, substantially as shown anddescribed.

2. lIhe combination, with the swinging arms or blocks geared to eachother, and provided with devices for guiding the rattan to thesplitting-cutter, of a flat pressure-spring cxtending around thepivot-heads in C form, with its ends pressing against the outer sides ofthe blocks, in the manner set forth.

3. The combination, with the swinging blocks or arms, pivoted as atf,and toothed together for simultaneous action, and provided with meansfor guiding a rattan to the splitting-cutter, of the fiat metal springarranged as shown, and provided with adj listing-screws,

the points of which enter depressions on the exterior of said arms forretaining and regu- 4o lating the parts, substantially as set forth..

4. The combination, with the swinging arms E, geared together, andcarrying devices for guiding the rattan to the splitting-cutter, of thesupport-bar A, adapted for vertical and 45 lateral adjustment, uponwhich said arms are pivoted and supported, as hcreinbefore set forth.

In a machine for splitting rattan, the combination, with the support-barA, having the 5o guiding devices mounted thereon, of the screwthreadedstuds B, fitted to the bed or frame for upholding said bar, and theclamp-bolts C, substantially as shown and described.

6. The combination of the guide-blocks piv- 55 oted for swinging action,and connected with each other for uniform operation by intel'- meshinggear-teeth, and means for adjusting the axis of their swing movement tocompelr sate for wear in the said gear-teeth. 6o

7. In a guiding device for rattan-splitting machines, an eccentricbushing, F, in combination with the pivot-studs f and guide-blocks E,provided with intermeshing gear-teeth c, as and for the purpose setforth. 65

8. rlhe combination, with the studs f and guide-blocks E, of aneccentric bushing, F, oi' slightly greater height than the thickness ofthe block, whereby said bushing is adapted to be clamped in position bysaid stud while the 7o block is free to swing thereon, .as set forth.

Vitness my hand this 7 th day of November,

GEORGE V. LOMBARD.
